FRED S. CARR, OF NEWTON, MASSACHUSETTS,ASSIGNOR TO CARR FASTENER COM- PANY, 0F CAMBRIDGE,MASSACHUSETTS, A CORPORATION OF MAINE.

APPARATUS FOR LOCATING SECURING PARTS OF SEPARABLE FASTENERS TO: CARRY- ING FABRICS.

Application filed January 16, 1920. Serial No. 351,782.

To all whom it may concern.

Be it known that I, FRED S. CARR, a citi zen of the United States, and resident of Newton, in the county of Middlesex and Commonwealtn of Massachusetts, have invented an Improvement in Apparatusfor Locating Securing Parts of Separable Fasteners to Carrying Fabrics, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to apparatus for locating securing parts of separable fasteners to carrying fabrics.

It is among the objects of the invention to provide convenient means for insuring correct alignment between cooperating stud and socket members attached to fabrics to be joined together, so as to avoid pulling or wrinkling of the fabric.

Referring to the drawings and to the preferred form of my invention selected for illustrative purposes:

Figure 1 is a side elevation of a preferred form of apparatus while locating, one relative to the other, the cooperating elements of separable fasteners when attaching the same to their carrying fabrics;

Fig. 2 is a plan view of the apparatus shown in Fig. 1, the fabric carrying the socket member, which has been initially applied, being turned back to permit sewing to its carrying fabric of the stud member;

Fig. 3 is a section, partly in elevation, on the line 8-3 of Fig. 2, showing the relation of the carrying fabrics, fastener parts, and gripping portions of the apparatus while locating a stud relative to its carrying fabric and relative to a socket member initially applied to the socket-carrying fabric; and

Fig. a is a view similar to Fig. 3, but showing the reverse thereof wherein a socket member is being located relative to its carrying fabric while being located relative to the stud which has been initially secured to the stud-carrying fabric.

Referring to the drawings and tothe preferred form of my invention selected for illustrative purposes, I have shown in Figs. 1, 2 and 3 the location of the stud 5 relative to the stud-carrying fabric 6 and relative to the socket member 7 which has been initially applied to the socket-carrying fabwhile permitting the head of the stud to engage the aperture in the socket during the locating operation, so that perfect registry may be attained.

One of the jaws, for example jaw 9, should be sufliciently thin to fit between the stud and socket members while the head of, the stud is entered in the socket, as

shown in Fig. 3. The same jaw preferablyhas an opening, notch or recess 12 therethrough for passage of the head of the stud to permit the jaw to engage with the neck of the stud as will be understood from Figs. 2 and 3. The notch or recess 12 locates the jaw definitely relative to the stud so that the stud is properly positioned and held preparatory to being permanently secured to fabric 6; It has been found preferable to formthe notch or recess- 12 so that it is tapered or somewhat V-shaped, as seen in Fig. 2, whereby the jaw recess accommodates studs of varying diameters, providing varying bearing points for the stud heads.

After the parts have been gripped in the relation shown in Fig. 3, the socket-carrying fabric with its attached socket may be turned back to leave the stud-carrying fabric 6 exposed, as shown in Fig. 2.

For some purposes, it may be desirable initially to apply the stud, in which case the locating means is utilized in the manner shown in Fig. 4, the socket 7 being gripped and located relative to its carrying fabric 6, while the head of the initially applied stud 5 is permitted to enter in the stud-receiving aperture of the socket. In this instance, the stud-carrying fabric 8 may, after the locating operation, be turned back, thereby leaving the sewing holes 11 in the socket 7 exposed to permit at least partial sewing of the socket to its carrying fabric while gripped thereagainst.

It will be understood that I use the word fabric in its broader sense to include Lml not only woven materials, but any flexible carrying medium, and that the word pliers is used in its broad sense to include tweezers or ,other gripping appliances.

i 'i hile I have shown and described a preferred form of appartus for locating, one relative to the other, the cooperating members of separable fasteners and a preferred method of locating such fasteners, it will be understood that major changes involving omission, alteration, substitution and reversal of parts of the apparatus and changes in the method of practicing the same may be effected without departing from the scope of my invention, as defined in the following claims.

Claims: V

1. An appliance for locating one relative to the other the stud and socket members cl L ara le fastener, said appliance havo'\VO relatively movable jaws at least one or which is uiliciently thin to fit between the stud and socket while the head of the stud is entered i the socket.

2. n appii :e for locating one relative the other the stud and socket members [separable fastener, said appliance providing two jaws at least one of which is iently thin to fit between the stud and socket while the head of the stud is entered in the socket aperture, said jaw having a recess therein for engaging the neck of the stud.

3. An appliance for locating one relative to the other the stud and socket members of a separable fastener, said appliance having two jaws at least one of which is sufiiciently thin to fit between the stud and socket while the head of the stud is entered in the socket, said jaw having a tapered aperture therein to provide varying bearing points therein for studs of varying diameters.

An appliance of the class described having two jaws capable of gripping between them either of the two members of a stud and socket fastener, one of said jaws having means adapted to engage with the neck of the stud to locate the jaw definitely relative to the stud, said jaw having a thickness materially less than the length of the stud body so as to it between the stud and socket when they are suiiiciently engaged to assure axial ali nement, said jaws being tapered at the ends so as to expose at least two of the thread apertures provided near the peripheries of both members of the fastener, whereby the member gripped between said jaws may be secured by sewing to a fabric while gripped by said jaws and will maintain its position on the fabric after being released.

In testimony whereof, I have signed my name to this specification.
